SPECIFICATION formingpart of Letters Patent No. 515,814, dated March 6,1894. Application filed December 14, 1898. Serial lie 493,627. (Nomodel.)

To all whom it may concern..-

Beitknown that LANToN BRAUN, a citizen of the United States, residing atNewport, Campbell county, Kentucky, have invented new and usefulImprovements in Screen- Frames for )Nindows, 850., of which thefollowing is a specification.

My invention relates to frames for windowscreens composed ofwire-netting or gauze, made to fit in the grooves of the sash or doorframe as a substitute for the sash or door, for the purpose of excludinginsects. It is necessary to have the frame as light as possible in orderto fit the narrow spaces of the door and window casings, and also inorder to maintain the screened opening to its utmost size, to admit airand light. Under these conditions, and because of the additional factthat the wire netting is to be retained in tension, the light framenecessarily warps or bends and the screen becomes unsightly, or bracesare placed between the sides of the screen frame across the screenedsurface, which are equally objectionable.

The objectof my invention is to produce a screen frame free from theobjections above referred to, and better adapted to answer theconditions of use.

To this end, my invention consists in a screen frame of wood or otherlight material, having embedded within the same a skeleton frame ofmetal to which the gauze or netting is secured, as hereinafterdescribed.

My invention is illustrated in the accompanying drawings, in which-Figure 1, is a plan view,-partly sectioned to show construction,of onecorner of my improved screen framecomplete. Fig. 2, is a cross sectionof the wooden part of the frame. Fig. 3, is a cross section of theentire composite frame. Fig. 4, is a plan view of one of the blanksemployed to unite the corners ofthe metal strips. Figs. 5 and 6, arecross sections showing the frame made of two pieces secured together,iuclosing a space to be occupied by the metal skeleton and avoidingthenecessity of an independent strip.

Referring now to the, drawings; A, designates the screen frame and, B,the wire netti'ng or gauze.

In the preferred form of construction, the

wooden frame, A, is made up of lengths of homogeneous strip grooved atone edge as at, g, in the section'Fig. 2. The skeleton metal frame, a,is made up of fiat rolled bars of ron or steel cut to length andpreferably joined at the corners (as in Fig. 1), by sheet metal blanks,b, (Fig. 6,) whose flaps, b, are folded upward over the metal strip uponthe dotted lines shown in Fig. 6, as shown in full lines in Fig. 1.Around a metal frame so made, the wire netting or gauze, B, is bent andtightly secured by the close fit of theiron frame, ,a, in the groove gas shown in Fig. 3. When the parts of the frame are placed together, afilling strip. 0, is glued or tacked in place as shown in Fig. 3, andthe corners of the composite frame are secured together by a diagonalscrew or rivet, d, (Fig. 1) or by exterior metal coverings (not shown).There is thus formed an exceedingly strong frame capable of resistingthe tension of the netting, and holding all parts securely together, andthe metal skeleton remains embedded and concealed in the wood. Arelatively smaller frame can thus be had, with far greater strength thanif composed of wood alone, and capable of always maintaining its properrectangular shape without cross braces.

The outer or wooden frame, A, can be made of two-part strips divided asindicated in Figs. 5 and 6.

I claim as my invention and desire to secure by Letters Patent of theUnited States 1. In a wire screen the combination of a recessed woodenframe, an inner strengthening skeleton of metal embedded in and fittingsaid recess, and a sheet of wire-netting extended at its edges into therecess of the wooden frame and engaged over the metal skeleton,substantially as set forth.

2. The combination of the recessed wooden frame, A, the metallic frame,a, wire gauze, B,

and filling strip, 0, substantially as set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

ANTON BRAUN.
